Safety information
Electrical safety
• To prevent electric shock hazard, disconnect the power cable from the electric outlet
before relocating the system.
• When adding or removing devices to or from the system, ensure that the power cables
for the devices are unplugged before the signal cables are connected. If possible,
disconnect all power cables from the existing system before you add a device.
• Before connecting or removing signal cables from the motherboard, ensure that all
power cables are unplugged.
• Seek professional assistance before using an adapter or extension cord. These devices
could interrupt the grounding circuit.
• Ensure that your power supply is set to the correct voltage in your area. If you are not
sure about the voltage of the electrical outlet you are using, contact your local power
company.
• If the power supply is broken, do not try to x it by yourself. Contact a qualied service
technician or your retailer.
Operation safety
• Before installing the motherboard and adding devices on it, carefully read all the manuals
that came with the package.
• Before using the product, ensure that all cables are correctly connected and the power
cables are not damaged. If you detect any damage, contact your dealer immediately.
• To avoid short circuits, keep paper clips, screws, and staples away from connectors,
slots, sockets, and circuitry.
• Avoid dust, humidity, and temperature extremes. Do not place the product in any area
where it may become wet.
• Place the product on a at and stable surface.

Thank you for buying an ASUS®P5KPL IN/SI motherboard!
Before you start installing the motherboard, and hardware devices on it, check the items in
your motherboard package. Refer to page ix for the list of accessories.
If any of the items is damaged or missing, contact your retailer.
1.1 Before you proceed
Take note of the following precautions before you install motherboard components or change
any motherboard settings.
• Unplug the power cord from the wall socket before touching any component.
• Use a grounded wrist strap or touch a safely grounded object or a metal object, such
as the power supply case, before handling components to avoid damaging them due to
static electricity
• Hold components by the edges to avoid touching the ICs on them.
• Whenever you uninstall any component, place it on a grounded antistatic pad or in the
bag that came with the component.
• Before you install or remove any component, ensure that the ATX power supply is
switched off or the power cord is detached from the power supply. Failure to do so may
cause severe damage to the motherboard, peripherals, or components.

Product introduction
Onboard LED
This motherboard comes with a standby power LED that lights up to indicate that the system
is ON, in sleep mode, or in soft-off mode. This is a reminder that you must shut down
the system and unplug the power cable before removing or plugging in any motherboard
component. The illustration below shows the location of the onboard LED.

1.4.1 Overview
The motherboard comes with two Double Data Rate 2 (DDR2) Dual Inline Memory Modules
(DIMM) sockets.
The gure illustrates the location of the DDR2 DIMM sockets:
• Ensure that all power cables are unplugged before installing the CPU.
• Upon purchase of the motherboard, make sure that the PnP cap is on the socket and
the socket contacts are not bent. Contact your retailer immediately if the PnP cap
is missing, or if you see any damage to the PnP cap/socket contacts/motherboard
components. ASUS will shoulder the cost of repair only if the damage is shipment/
transit-related.
• Keep the cap after installing the motherboard. ASUS will process Return Merchandise
Authorization (RMA) requests only if the motherboard comes with the cap on the
LGA775 socket.
• The product warranty does not cover damage to the socket contacts resulting from
incorrect CPU installation/removal, or misplacement/loss/incorrect removal of the PnP
cap.
1.4.2 Memory congurations
You may install 512MB, 1GB, and 2GB unbuffered non-ECC DDR2 DIMMs into the DIMM
sockets.
1-3 ASUS P5KPL IN/SI

• You may install varying memory sizes in Channel A and Channel B. The system maps
the total size of the lower-sized channel for the dual-channel conguration. Any excess
memory from the higher-sized channel is then mapped for single-channel operation.
• Always install DIMMs with the same CAS latency. For optimum compatibility, we
recommend that you obtain memory modules from the same vendor.
• Due to the memory address limitation on 32-bit Windows OS, when you install 4GB
or more memory on the motherboard, the actual usable memory for the OS can be
about 3GB or less. For effective use of memory, we recommend that you install a 64-bit
Windows OS when having 4GB or more memory installed on the motherboard.
• The default memory operation frequency depends on its SPD. Under the default state,
some memory modules for overclocking may operate at a lower frequency than the
vendor-marked value.
• For system stability, use a more efcient cooling system to support a full memory load
(2 DIMMs) or overclocking conditions.

1.6 Jumpers
1. USB device wake-up (3-pin USBPW1-4, USBPW5-8)
Set this to +5V to wake up the computer from S1 sleep mode (CPU stopped, DRAM
refreshed, system running in low power mode) using the connected USB devices. Set
to +5VSB to wake up from S3 and S4 sleep modes (no power to CPU, DRAM in slow
refresh, power supply in reduced power mode).

• The USB device wake-up feature requires a power supply that can provide 500mA on
the +5VSB lead for the USB port. Otherwise, the system would not power up.
• The total current consumed must NOT exceed the power supply capability (+5VSB)
whether under normal condition or in sleep mode.
Chapter 1: Product introduction 1-6

2. Clear RTC RAM (CLRTC)
This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. You can
clear the CMOS memory of date, time, and system setup parameters by erasing
the CMOS RTC RAM data. The onboard button cell battery powers the RAM data in
CMOS, which include system setup information such as system •words.
To erase the RTC RAM:
1. Turn OFF the computer and unplug the power cord.
2. Remove the onboard battery.
3. Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the cap on pins 2-3
for about 5~10 seconds, then move the cap back to pins 1-2.
4. Reinstall the battery.
5. Plug the power cord and turn ON the computer.
6. Hold down the <Del> key during the boot process and enter BIOS setup to re-
enter data.
Except when clearing the RTC RAM, never remove the cap on CLRTC jumper default
position. Removing the cap will cause system boot failure!

• If the steps above do not help, remove the onboard battery and move the jumper again
to clear the CMOS RTC RAM data. After the CMOS clearance, reinstall the battery.
• You do not need to clear the RTC when the system hangs due to overclocking. For
system failure due to overclocking, use the CPU Parameter Recall (C.P.R.) feature. Shut
down and reboot the system, then the BIOS automatically resets the parameter settings
to default values.
• Due to the chipset limitation, AC power off is required before you use the C.P.R.
function. You must turn off and on the power supply or unplug and plug the power cord
before rebooting the system.

3. Keyboard/mouse power (3-pin KBPWR)
This jumper allows you to enable or disable the keyboard/mouse and USB port 5-6
wake-up feature. When you set this jumper to pins 2-3 (+5VSB), you can wake up the
computer by pressing a key on the keyboard (the default is the Space Bar), clicking
the mouse, or using a USB device. This feature requires an ATX power supply that can
supply at least 1A on the +5VSB lead, and a corresponding setting in the BIOS. The
USBPW56 jumper is for the rear USB ports.

4. CPU fan connector (4-pin CPU_FAN)
The fan connectors support cooling fans of 350 mA ~ 2000 mA (24 W max.) or a total
of 1 A ~ 7 A (84 W max.) at +12V. Connect the fan cables to the fan connectors on the
motherboard, ensuring that the black wire of each cable matches the ground pin of the
connector.
Do not forget to connect the fan cables to the fan connectors. Insufcient air ow inside the
system may damage the motherboard components. These are not jumpers! Do not place
jumper caps on the fan connectors!
Only the CPU_FAN
connector support the ASUS
Advanced Q-Fan feature.

• For a fully congured system, we recommend that you use a power supply unit (PSU)
that complies with EATX 12 V Specication 2.0 (or later version) and provides a
minimum power of 400 W.
• Do not forget to connect the 4-pin ATX12V power plug. Otherwise, the system will not
boot.
• We recommended that you use a PSU with a higher power output when conguring a
system with more power-consuming devices. The system may become unstable or may
not boot up if the power is inadequate.
